Boats are moored at the marina, as well as offshore. Some boats are on the beach, waiting to launch. A few small islands are visible in the background. Las Vegas Bay is a bay at the western edge of Lake Mead, to the northeast of the city of Henderson, Nevada, near the junction of Lake Mead Drive and Lake Mead Boulevard. A public campground and boat access are available in Las Vegas Bay. Low water levels of Lake Mead have rendered the marina there inoperable, and it relocated to the Hemenway Boat Harbor, in the south end of the Boulder Basin in 2002. The launch ramp there has also been closed due to the water levels. The Lake Mead Marina was relocated to the Hemenway Boat Harbor in 2008. The bay is the natural discharge point for the Las Vegas Wash. Las Vegas Wash is in the southeastern portion of the Las Vegas Valley and is approximately 12 miles long, from its headwaters northwest of Las Vegas to its mouth at Las Vegas Bay on the western portion of Lake Mead. The bridge across the Wash on Northshore Road is approximately 1.2 miles north of the intersection of Lakeshore and Northshore Roads.
